Stair treads, often referred to as steel ladder treads or grating treads, are essential components used on steel grating platforms and ladders. Depending on the installation method, these treads typically come in two varieties: those that are welded and those that are bolted. As their name suggests, they're designed primarily for use on steel ladders and are commonly known as stair tread plates.
(1) Based on how they're installed, stair treads can either be welded in place or bolted. Welded treads are standard grating panels that are permanently attached, while bolted treads require additional side plates—usually 65x5mm flat steel pieces—to secure them onto the grating.
(2) When considering anti-slip features, there are two main categories: tread plates with front guards (either patterned or ribbed steel) and those without. For safety reasons, we recommend using tread plates with front guards. There are four primary types of tread plates: T1, T2, T3, and T4.
The T1 tread plate is the most basic and cost-effective option. It features load-bearing flat steel and crossbars spaced at regular intervals. Typically, these are welded directly onto the grating and then hot-dip galvanized. Due to its affordability, this type is quite popular among customers looking for steel grating panels.
The T2 tread plate is similar to the T1 but includes side plate bolts for attachment. This design makes it easier to install and is commonly found on steel ladders.
The T3 tread plate builds upon the T1 model by adding a protective front guard along the length of the flat steel. The anti-slip front guard is usually made from patterned steel, enhancing the tread's slip resistance.
The T4 tread plate combines the features of both T2 and T3 models. It offers both anti-slip protection and installation slots. Welded treads are directly welded to the ladder beams, eliminating the need for additional side plates. While this makes them more economical and long-lasting, they can be challenging to remove. Bolted treads, on the other hand, require thicker side plates with holes, allowing them to be securely fastened with bolts and reused if necessary. Customers can customize their selection based on specific requirements, choosing appropriate types of grating to create various sizes that fit perfectly with corresponding staircases."
